## Algorithm

Problem Name: Python - Finding the percentage

In this HackerRank Functions in PYTHON problem solution,

The provided code stub will read in a dictionary containing key/value pairs of name:[marks] for a list of students. Print the average of the marks array for the student name provided, showing 2 places after the decimal.

Example

marks key: value pairs are

"alpha": [20,30,40]

'beta': [30,50,70]

queary_name = 'beta'

The query_name is 'beta'. beta's average score is [30 + 50 +70) / 3 = 50.0

Input Format

The first line contains the integer n, the number of students' records. The next n lines contain the names and marks obtained by a student, each value separated by a space. The final line contains query_name, the name of a student to query.

Constraints

• 2 <= n <= 10
• 0 <=marks[i] <= 100
• length marks of array = 3

Output Format

Print one line: The average of the marks obtained by the particular student correct to 2 decimal places.

Sample Input 0

```3
Krishna 67 68 69
Arjun 70 98 63
Malika 52 56 60
Malika
```

Sample Output 0

```56.00
```
